How to Choose High-Quality In Shell Pistachios: A Buyer’s Guide

Craving pistachios but not sure how to pick the best ones?

We’ve all been there. Pistachios are one of the most satisfying nuts to snack on, but choosing high-quality pistachios can be tricky, especially if you’re new to these delicious green nuts.

If you're reading this blog, chances are you're planning to buy some roasted in shell pistachios (pistachios with shell) soon. Or maybe you just want to learn more and get answers to your pistachio-related questions. Either way, we’re here to help!

By the end of this guide, you’ll feel more confident about choosing the best pistachios for your next snacking session.

5 Ways to Determine High-Quality Roasted In Shell Pistachios

1. Naturally open shells are the best

Pistachios come in different forms: in shell pistachios (pistachios with shell) or shell-less / shelled pistachios (kernels only). For in shell pistachios, there are two types you will commonly see: naturally opened shells and closed shells.

Most people are familiar with pistachios that have naturally open shells, and there is a good reason they are more popular. An open shell usually means the pistachio is fully ripe and ready to eat.

However, not all open-shell pistachios open on their own. Some pistachios are mechanically opened, which means they were harvested with closed shells and later cracked open by machines. While still edible, these pistachios often have lower quality compared to naturally opened ones.

Mechanically opened pistachios are often less mature, so the kernels can be smaller, shriveled, underdeveloped, or unripe. This can negatively affect the pistachio’s flavor and texture.

For the best snacking experience, it is better to choose naturally opened in shell pistachios. Fully mature pistachios naturally split their shells as the kernels grow larger. This results in pistachios that have bigger kernels, better flavor, and a more enjoyable texture compared to closed-shell or mechanically opened pistachios.

How to Identify Naturally Opened Pistachios

• The shell opening looks slightly irregular, not perfectly even.
• The shell edges are smooth, with no sign of forced cracking.
• The kernels are easily visible inside the opening.
• There are no unusual cracks running down the shell.

Choosing naturally opened pistachios helps ensure you get the best quality, taste, and freshness for the best snacking experience. And if you are ready to buy one, check out our in shell pistachios here!

2. Look for the best kernel and shell color

Of course, color is a big deal when it comes to pistachios.

Let’s start with the kernels. Pistachio nuts are well known for their vibrant green color. This natural color comes from chlorophyll, the green pigment that helps plants survive. If you want to learn more about the simple but fascinating science behind their green hue, check out this article.

The best-quality pistachios have kernels that are bright green with hints of yellow and purple. New harvest pistachios usually have the greenest kernels.

As time passes after harvest, the green color can fade slightly, turning more yellow-green or even yellowish. They are still completely edible and delicious, but nothing beats the rich color and fresh flavor of a new harvest.

Older pistachio kernels or those of lower quality often look pale, dull, brownish, or slightly shriveled.

Now let’s talk about the shell color. High-quality pistachios usually have shells that are beige or ivory. Naturally grown pistachios also have slight speckles and a matte appearance. This is especially true for pistachios harvested in the United States.

If the shells look unnaturally bright white, overly clean, or highly polished, there is a good chance they were chemically bleached to make them appear fresher. This is often done to older harvests or lower-quality crops.

3. A fresh pistachio nut must also smell "fresh"

You should also check the smell of your pistachios to determine their freshness. This is simple and effective.

Fresh pistachios have a nutty, warm aroma with a hint of sweetness. They should never have a sour, musty, or rancid smell.

A simple rule to remember is that pistachios should not smell offensive. As a natural product, the best pistachios should smell fresh and natural.

Next time you buy pistachios, don’t just focus on the color. Make sure to check the smell as well to ensure the best quality and taste.

4. A perfect roasted pistachio has a perfect roasting quality

Most in-shell pistachios on the market are roasted, just like our mmmm Pistachios! Many consumers love these roasted pistachios for snacking.

Roasting is where the magic happens. It brings out the flavor, crunch, and aroma of these green gems. However, not all roasted pistachios are roasted properly, which can affect their taste, color, and overall quality.

If you are looking for high-quality roasted pistachios, check the color. They should be roasted evenly with no burnt spots. Dark or black spots on the shell or kernel usually indicate over-roasting or burning.

Burnt pistachios develop a bitter, acrid taste that can overpower their natural nutty flavor. The texture becomes drier and harder, rather than crisp and crunchy. Additionally, improperly roasted pistachios may lose some nutrients, reducing their overall health benefits.

Always choose pistachios that are evenly roasted to enjoy the best taste, texture, and nutrition.

5. Quality packaging for quality pistachio nuts

Lastly, it is important to make sure that the pistachios you are buying are packaged properly using high-quality and appropriate materials.
